By studying the stock market, however, many researchers discover that the stock prices do not obey the geometry Brownian movement, i.e., the logarithm return rate of stock prices do not obey normal distribution.

然而大多研究者通过对股市的研究发现股票价格并不服从几何布朗运动，即对数收益率不服从正态分布，如文献[6][7]通过对实测数据的分析，说明布朗运动与市场实际相距甚远。

In the article, the numerical simulation software ANSYS is used to analyze the working stress distribution in butt joint and the effect of the geometric parameter on the stress concentration efficiency .

摘要通过数值模拟软件ANSYS分析对接接头的工作应力分布，找出了对接接头的几何参数对应力集中系数的影响。

(1) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.

(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

The influences of chemical bonding, molecular structure and charge distribution on the electron correlation are also discussed.

Modal analysis of an acoustic system can determine its natural frequency and show the distribution of the acoustic quantities in space, give the knowledge about the way that the acoustic system responses are affected when changes are made in the excitation sources or in the domain geometry, and provide valuable information for the noise control of closed three-dimension domain.

通过对声学系统的模态分析，可以得到其固有频率以及在此频率下声学量在声场空间上的分布，了解到声源及声场空间几何参数的变化对声学系统的相应的影响，为三维封闭空间的噪声控制提供了依据。

Such as measurement of refractive index distribution is one of the most important test, and thus can be measured optical fiber preform of a series of geometric parameters such as core / package ratio, concentricity, roundness and so on.

比如折射率分布测量就是其中一项最重要的测试，并由此可测得光纤预制棒的一系列几何参数，如芯/包比、同心度、不圆度等。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
